Here’s a view from local.live of the block front were the Empress was situated. The address corresponds to the storefronts immediately adjacent to the Temple of Islam building on the corner of Lenox Avenue – which is the big yellow and buff 3-story structure with the large green bulb on top.

The Empress would have been in the low lying building on the Temple’s right – with 1 green storefront and 1 yellow and white upper facade. If, in fact, this is the same structure.
